Claims.

My invention relates to a closure for the end of a roller bearing and has for its principal object a closure which is elective but of simple construe-- tion and which can be used to make a self-con- 5 tained assembly of the bearing.'

Theinvention consists principally in a closure having spaced outer cover rings and spaced inner cover rings arranged in alinement with each other and an annular washer or diaphragm bridging the gap between two sets of cover rings and with its ends held between the cover rings of the respective sets. The invention further consists in the bearing closure and in the parts and combinations and arrangements'of parts Hereinafter described and claimed.

In the accompanying drawing, Fig. l is a sectional view of a bearing and of closure therefor embodying my invention; Fig. 2 is a sectional view of a modified closure; Fig. 3 is a sectional view of another modification; and

Fig. 4 is a view of another modification. In Fig. 1 is illustrated a taper'rollerbearing including a cup I vor outer bearing member, conical 5 rollers 2 and a cone 3A or inner bearing member having a thrust rib 4 for the rollers at its large end and. having a cylindrical portion 5 extending beyond the small end of the raceway.

The cup has a rabbeted portion 6 in the end opposed to the cylindrical portion 5 of said cone. Mounted in said rabbet B are radially disposed at outer cover rings 1 or washers having a spacer ring 8 therebetween, the ring assembly being held together by means of rivets 9. The innermost 35 outer cover ring 1 abuts against the shoulder I0 formed by the rabbet 6 and the outermost outer cover ring 1 is ilush with the edge of the cup I. The spacer ring 8 is relatively narrow and disposed between the outer portions of the cover rings 1. l

Mounted on the cylindrical portion 5 of the bearing cone 3 are :tlat inner cover rings II or washers and a spacer ring I2 therebetween, the 45 ring assembly being held -together by means of rivets I3. The inner cover rings Ilyare in aline? ment with the respective outer cover rings 1, there being an annular gap I4 between the outer peripheries oi' the inner cover rings and the inner 50 peripheries of the outer cover rings. Disposed in the annular chamber i5 formed by the outer cover rings 1,'the inner cover rings I I, the outer spacer ring 8 and the inner spacer ring I2, is an annular diaphragm I6 or washer. 'Ihis `diagg phragm I6"is of asize. toflt loosely in saidl cham- (clv. zas-1) facture andvarlatio ber so as to accommodate irregularities of manuns in the sizes .o f parts.

In the construction shown in Fig. 2, there is a center ring 20 of the same construction as the outer cover rings 1, of said center ring cover rings.

spacer rings 8 on either side s spacing it from the outer Similarly there is an inner center ringI 2| in the inner ring assembly -in ,alinement with the outer cente vided a second ann second diaphragm 2 r ring 20. There is thus proular chamber 22 in which a 3 is mounted.

.In the construction shown in Fig. 3, the spacer rings are eliminated, the cover rings 30 being of Vangular section with nested peripheral portions 3I and radial ilanges 32. 'I'he overlapping edge portions 33 of the peripheral flange portions of the cover rings are spun over the inside rings to hold the parts in assembly.

The modification shown in Fig. 4 includes an outer cover havingradial ilanges 4I at its ends, a center ring 4 rings 43 holding the center ring 42 in position.

2 mounted therein and spacer Y The outer cover ring initially has a radial iiange at one end only, a projecting cylindrical portion 44 indicated in dotted lines being spun over after the center ring and spacer rings have been mountedy to form the second radial ilange.

The inner member ot the closure likewise includes an inner cover 45 having radial end iianges 46, a center ring 41 and spacer rings 48 mounted in said inner cover on either side of said center rings. One ilange of said inner cover 45 is formed by spinning over a cylindrical portion 49, shown in dotted lines, after the parts have been assembled.

The above describ ed closures make of the bearing a self-contained unit. The closure is simple in construction, can

be made cheaply of stamped parts and forms a very eiective seal. Obviously numerous changes may be made without departing from the invention and I do not wish to be limited to the precise construction shown.

What I claim is:

1. A bearing closure radialspaced radial cover comprising outer spaced cover rings, securing means therefor, inner rings in alinement with the respective outer cover rings and spaced radially therefrom, securing and a floating diap ,means for'said inner rings, hragm bridging the gap bethe outer cover rings tion disposed betwee and its inner peripheral porn the inner cover rings.

2. A bearing closure comprising outer spaced radial cover rings, rivets securing said a spacer ring therebetween,

cover rings and spacer rings ing diaphragm bridging the gap between the inner l and outer sets of cover rings, with its outer peripheral 4portion disposed between the outer cover rings and its inner peripheral portion dis.-

posed between the innercover rings.

3, A bearing closure comprising aiplurality of outer spaced radial cover rings, spacer rings between adiacent cover rings, rivets securing the ring assembly together, a plurality of inner spaced radial cover rings in alinement with the respectiveouter cover rings and spaced radially therefrom, spacer rings between adjacent inner cover rings, rivets securing said inner ring assembly together, and oating diaphragms bridging the gap between the inner and outer sets of cover rings. with their outer peripheral portions disposed between vouter cover rings and their inner peripheral portions disposed between inner cover rings.

4. A bearing closure comprising a pair of angular outer cover rings having tions nested and their radial flanges spaced apart,

yand spacer'v rings.

their peripheral pora pair of angular inner coverrings having their peripheral portions nested and their radial flanges spaced apart and radially alined with theA radial flanges of said outer cover rings and an annular oating diaphragm bridging the gap between inner and outer cover rings, its outer periphery be-` ing disposed between said outer 'cover rings and its inner periphery between said inner cover rings.

5. A bearing ring and the end flanges of said inner cover andl annular diaphragms in the chambers vformed by said center rings and the respective end flanges ALBERT' H. GOIDSWORTHY.
